Chinese Continental Shelf (IMAGE)
Caption
Portion of the world topographic map, highlighting the continental China and its adjacent land and seas (Google Map, 2015) to illustrate: (1) the Chinese continental shelf (basement of the East and South China Seas) to be of exotic origin; (2) arrival of the buoyant and unsubductable oceanic plateau or micro-continent at the trench jammed the trench at ~ 100 Ma; (3) the jammed trench location is shown in red dashed curve along the southeast coast of continental China although it is unclear in the north as indicated by the dashed light blue curve with question marks; (4) The yellow "drop" dots are granitoid sample locations with ages in the literature. The thick dashed purple line labeled E-W GGL approximates the East-West Great Gradient Line topographically separating the plateau to the west from the low-land hilly plain to the east.
